Mackay, ID

Set in the Big Lost River Valley beneath the White Knob Mountains, Mackay is home to around 450 residents. Locals pronounce it “Mackie,” a handy tip for anyone getting to know the area. Life here moves at a relaxed pace shaped by working cattle ranches, big open skies, and mountain views. Highway 93 runs straight through town, connecting you to Arco to the south and Challis to the north while keeping everyday life quiet and grounded.

The town grew out of a turn-of-the-century copper boom, leaving behind a historic brick Main Street and old mining roads that wind up into the foothills. Today, daily life centers on the outdoors and close neighborhood ties. Living in Mackay puts excellent trout fishing on the Big Lost River, boating on Mackay Reservoir, and hundreds of miles of off-road and hiking trails right outside your door.
